' ATOMIZER Amb'rrrn arms".

To all whom it mat concern:

Be i known thatT, OWEN DAVID LUCAS, a subjectof His Majesty the Kingof Eng land, residin at Bayswater, in the county of London, in e Kingdom of England, have invented1certain newand useful Improvements inAtomizers and the Like, of which the following is a specification.

Thisinvention relates-to improved means and apparatus for the automizing and vaporization of liquitls, whereby a very fine subdivision of the. liquid is obtained and complete vaporization is rendered ossible. The apparatus is capable of giving intimate mixture of air or other gas and vapor ar any desired proportions.

According to one form at the present invention I employ a number of independent capillary tubes of'glass, steel, or other suitable material; of any suitable lengthg Each such tube isbent at right angles at some point in its length and a number-of such bent tubes-ears grouped around an axis so that several tubes lie in juxtaposition up to the bend and the bent portions radiate from the axis in a plane perpendicular to the, same; The axis may as shown be arranged vertically and the upper or lowerends of the tubes are immersed in the liquid to be atomized, which is preferably kept at a more or less constant level in any of the well known ways. The group of tubes or element- 1s now-caused to rotate about the vertical axis and the eifectof the rotation is to project the liquid-from the bpen ends of the radiatingportions of the tubes into the sur rounding space in an exceedingly fine'spray.

the tubes is above the point tolwhich the liquid will rise by capillary attraction. However the action when the'liquid is up to the bend is more ra idxand more liquid will be vaporized in a given time Thus the rate of atomization of liquid can be varied by altertubes dip and-by altering thespeed of rotation.' Itfwill be found that every liquid reqlpires a capillary of particular bore to i give t ebest resultsa The invention is illustrated in the accom panying drawings .which:-

Figure 1 1s a sect onal elevation of complete apparatus constructed for use iniconl the wings or vanes thereon. Fig.3 is a similar view to ,Fig. 1 of a slightly modified form of apparatus in which the tubes and their support are mounted in a relatively inverted position Figs. 4 and 5 aresimilar views to Fig. 2 of the tube supporting disk tion as far as application will allow.

In carrying out this invention andreferring more particularly to Figs. '1 and 2 of the drawings,T make my tubes a--a of glass tubes are mounted and cemented on or to a support I) of celluloid, metal, wood,'or other material not acted on b the li u'id, and are arranged so that the horizontal l mbs The 1i uid is fed into the tube f from below, from t e float feed chamber m or other suitable level maintaining means through a pipe 71 and may be kept at a constant level in it or varied by adjusting the float in the known manner.

Rotation is imparted to the apparatus shown in the drawing, by inclosing it in a \gylindrical case 7' and providing the support with inclined-wings la-7c, siren ho es 70 (Fig. 4:), or turbine blades 70 (Fig. 5). The wings are as shown operated upon and the device thereby rotated by the current of air viously stated, the rotating capillaryelement into the tube fsurrounding the vertical PQI'. .tions of the tubes at. The tube 7 tests bn the of the tubes a depend into a tube or receptacle j" containing thediquid to be atomized; 7

caused by the suction of the engine and for this purpose the lower part of the casing 9" In themodified arrangement'ias shown in i provided respectively with siren holes and turbine blades. I

. Like letters of reference are employed to denote like parts throughout the specificaglass andbend them at right angles. These" too is mounted in a-relatively inverted positidn, the liquid-to be atomized is admitted directly Fig. 2 is a planet the tubes and theirsup v support 6; which is provided with wings 7c, porting element showing the arrangement of A "as in Fig. 1, and which carries the tubes a.

1 actual cap The support is provided with a centrally arranged spindle (2 having .-upper and lower end bearings g, h. The support is rotated in the same manner-as that described in Fig. l 5 and the liquid may be supplied and maintained at; the required level by any suitablewell known means. It will thus be seen that,

- the level of the liquid into which the vertical portions of the tubes vare'placed will have someinfiuence on the flow of-the liquid fromthe tubes for instance if the level were lowered in Fig. 1 a greater s ed of rotation shown in Fig. 1 and the level of the liquid is above the. ends of,the tubes the liquid will not flow therefrom when the apparatus is at rest.

The tube element could be rotated mechan-ically by. gearing it to some rotating part of the englre by means of a belt, pinion gear, or other means.

This invention is also suitable for atomizing liquids for furnaces and the like, when the apparatus may be rotated as before mechanically or by the blast of air employed in'the furnace or by injectingsteam under pressure, or steam and air.

I may if desired inclo'se the apparatus in a jacketed cylinder Z or other chamber provided with means of keeping the said chamher hot or cold.

What Iclainianddesirb to secure by Let-- ters Patent of the United States is-:

1. An atomi'zing apparatus comprising a vertically arranged liquid-containing vessel,

a series of independent capillary tubes extendin into sai vessel having their ends arrangef below the liquid level therein and whose lengths are so proportioned in relationto their diameters that the liquid will not normally flow out of them when the a paratus is at rest, a support on which the ubes are mounted, means for rotatin the support and means for supplying. liquid in proper quantities to the tu es.

3. An atomizing apparatus com rising a rotatable support, a series of indgpendent bent tubes carried thereby and havmg vertical portions connected with horizon al radial portions, a supply tube into which the vertical ortions extend, means for supplying liquid in means for rotating t e tube support.

In testimony whereof, I have hereiinto subscribed my name.
